Moses' prophetic song based on the people's foreknown fall

We have the prophetic song, which is based on the foreknown fall
of the people. First, it declares the perfectness of Jehovah,
whatever may take place; it is Israel who have corrupted themselves
(compare Ps. 22: 3. Christ can say, "Why?") At the same time
(ver. 8) we have an all-important declaration; namely, that God, in
His government of the world, had made Israel the centre, and had
arranged the nations of the earth, in their various localities, as
having respect to the bounds of Israel as being the first object of
those ways. For His earthly people are Jehovah's portion, His
inheritance upon earth. But Jeshurun (Israel) waxed fat, and kicked,
and forsook the Rock of his strength. Consequently God moves them to
jealousy with those that are not a people. It is the call of the
Gentiles, according to Romans 10: 19.

God's ways with Israel and the Gentiles

The judgment, nevertheless, falls upon Israel, so that God would
have destroyed them, had not the glory of His name hindered Him, for
the Gentiles proved themselves perfectly wicked. Then, the people
being distressed, without strength and without hope, He remembers
them, and finally takes vengeance on their enemies, those idolatrous
Gentiles. But, though avenging Himself, it is then that, having
restored His people Israel, He will cause the Gentiles to rejoice in
Him.

Israel yet to be restored, and God's mercy shown to His land
and His people

This principle is true already; but the testimony it furnishes
will be fully accomplished when Israel is again restored to the
enjoyment of the promises; when God will manifest His mercy towards
His land, as well as towards His people. The whole course of His
dealings, in respect of the people who form the centre of His ways
upon earth, is thus fully brought out. Afterwards, Moses puts
obedience (the great end of this book, Israel being placed under the
condition of obedience for continuance in the enjoyment of the
promises) before them again, and reminds them that thereby they would
prolong their days in the land which they were going up to
possess.

Moses' sight of the land

At last poor Moses has to go up Mount Nebo, to see the land into
which he cannot enter, not having answered the requirement of the
glory of God in the wilderness, nor sanctified His name by faith. It
is the unavoidable consequence of the just government of God towards
a servant -- I mean under the law. He does not get into the enjoyment
of the promise. A single fault deprives him of it.
